Exploring the Existence of Local and Global Knowledge Spillovers: Evidence from Plant‐Level Data*
利用爱尔兰制造业工厂数据，研究国内和跨国知识溢出效应，发现国内工厂受益于其他国内工厂及外资母国研发活动，且全球溢出受距离衰减影响较小。
Abstract We investigate the existence of local (within‐country) and global (between‐country) knowledge spillovers within a single analytical framework. Our study is based on a detailed database of domestically owned and foreign‐affiliated manufacturing plants located in Ireland. The results of our econometric analysis show that domestically owned plants benefit from the research and development (R&D) activities of other domestically owned plants, as well as from R&D activities conducted in the country of origin of foreign‐owned plants through their presence in Ireland. A fundamental difference between such locally generated and locally transmitted global spillovers appears to be that the latter are much less constrained by distance decay effects.
